#eix xfce4-session
[I] xfce-base/xfce4-session
     Available versions:  4.10.0-r1 4.10.1 {consolekit debug gnome-keyring policykit systemd udev +xscreensaver}
     Installed versions:  4.10.1(08:17:51 AM 01/11/2014)(systemd udev -debug -xscreensaver)
     Homepage:            http://docs.xfce.org/xfce/xfce4-session/start
     Description:         A session manager for the Xfce desktop environment

$grep xfce .xinitrc
exec startxfce4

I follow several major linux distros as VirtualBox guests, and the only one
that doesn't force the use of a display manager is arch linux, so I use
startx on arch and I still see ACTIVE=1 in gnome3, cinnamon, etc.

I'll try to debug this over the weekend when I'm more awake :)

Thanks Canek.
